TECHNICAL FIELD

The present invention relates to a substrate for a touch screen sensor,a touch screen sensor, and a touch screen panel including the same. Moreparticularly, the present invention relates to a substrate for a touchscreen sensor for reducing visibility of a sensing pattern provided inorder to sense a touch signal of a user in a touch screen sensor, atouch screen sensor, and a manufacturing method thereof.

BACKGROUND ART

A touch screen panel, as an input and output means for sensing a touchposition of a user on a display screen and receiving information on thesensed touch position to perform an overall control of an electronicdevice including a display screen control, is a device which recognizesa touch as an input signal when an object such as a finger or a touchpen is touched on a screen. The touch input device has been mainlymounted on a mobile device such as a mobile phone, personal digitalassistants (PDA), and a portable multimedia player (PMP) in recentyears. The touch input device is being used throughout overallindustries such as a navigation, a netbook, a notebook, a digitalinformation device (DID), a desktop computer using an operating systemthat supports touch input, an internet protocol TV (IPTV), astate-of-the-art fighter, a tank, and an armored vehicle.

However, since the touch panel is added on a display device such as aliquid crystal display (LCD), a plasma display panel (PDP), an organiclight emitting diode (OLED), and an active matrix organic light emittingdiode (AMOLED) or embedded in the display device, there is a problem invisibility for a user.

DETAILED DESCRIPTION OF THE INVENTION Technical Problem

In order to solve the problem in visibility, in a touch screen sensorincluding an ITO transparent electrode in the related art, sensing andoperating sensors are formed by patterning a transparent electrodematerial (ITO), and since recognition for a changed value of capacitanceis deteriorated due to high specific resistance of the ITO material as adistance between the sensing and operating sensors is increased and adistance between a touching finger and the sensor is increased, there isa limit to use a high-transparent and high-durable base. The touchscreen panel in the related art has a problem in that a pattern isrecognized, in the case where an electrode layer is formed of a materialother than ITO and thus a dimensional difference of the operating andsensing patterns exists due to opacity of the electric layer.

Technical Solution

In thisdescription, when any component is connected to another component, anycomponent may be directly connected to another component and may also beconnected to another component with a third component interposedtherebetween. First, in adding reference numerals to componentsthroughout the drawings, it is to be noted that like or similarreference numerals designate like or similar components even though thecomponents are illustrated in different drawings. In this case,configuration and operation of the present invention which areillustrated in the drawings and described as those illustrated in thedrawings are described as at least one exemplary embodiment, and thespirit and main configurations and operations of the present inventionare not limited thereto.

Before describing exemplary embodiments of the present invention,several terms used in this specification will be described. First, theterm “substrate” is used for manufacturing a touch screen sensor, andmay also be called a “film” in this specification. A touch screen sensormay be manufactured by singly forming the substrate or forming twosheets of substrates as an upper substrate and a lower substrate toadhere to each other.

Hereinafter, an exemplary embodiment of the present invention will bedescribed.

FIGS. 1A and 1B are exemplified diagrams illustrating a sensing unit 110and a connecting unit 120 in a substrate for a touch screen sensor inthe related art to be solved in the present invention. Referring toFIGS. 1A and 1B, the sensing unit 110 in the related art is formed aselectrodes connected to each other in a pattern of a predetermineddirection on one side of a base, but since the connecting unit 120 isformed as electrodes connected to each other in a different pattern fromthe sensing unit 110, there is a problem in that visibility of thesensing unit 110 and the connecting unit 120 is increased due to adifference between the patterns as continuity of the electrodesdisappears. Edges of the sensing unit 110 or the connecting unit 120 areconnected to each other by edge electrodes, such that continuity of theelectrodes disappears, thereby increasing the visibility of the sensingunit 110 or the connecting unit 120 in the related art.

Accordingly, in order to solve the increase in the visibility of thesensing unit 110 in the related art, the present invention provides asubstrate for a touch screen sensor having the same or similar patternsof the sensing unit 110 and the connecting unit 120 connecting thesensing unit 110.

FIG. 2A is an exemplified diagram illustrating a sensing unit and aconnecting unit of a substrate for a touch screen sensor according to anexemplary embodiment of the present invention. Referring to FIG. 2A, asubstrate for a touch screen sensor according to the exemplaryembodiment includes a plurality of sensing units 110 formed byelectrodes connected to each other in a pattern having a predetermineddirection on one side of a base and connecting units 120 formed byelectrodes connected to each other in a pattern having the same or asimilar direction as or to the pattern, and connecting the sensing units110.

Referring to FIG. 2B, the substrate for a touch screen sensor accordingto the exemplary embodiment may further include a plurality of dummyunits 110′ which are adjacent to the sensing units 110 and formed byelectrodes connected to each other in a pattern having the same or asimilar direction as or to the patterns to reduce visibility of thesensing units 110 and connecting units (not shown) which are formed byelectrodes connected to each other in a pattern having the same or asimilar direction as or to the pattern and connecting the dummy units110′.

Here, the sensing unit 110, as an electrode provided in order to sense atouch signal of a user, is made of a conductive material in the presentinvention, and the conductive material may be opaque.

The dummy unit 110′ is an electrode by neighboring with or beingadjacent to the sensing unit 110, and means an electrode formed in aninactive state or a combination thereof which is formed in a dummy, thatis, a pattern having a similar shape to the sensing unit 110 so as notto sense the touch signal of the user. Accordingly, the sensing unit 110and the dummy unit 110′ are formed to be electrically insulated fromeach other. The reason why the dummy unit 110′ is formed on the base isthat the sensing unit 110 which is not made of a transparent electrodematerial is formed on the front side of the touch screen sensor toprevent the sensing unit 110 from being recognized by external lightirradiated to the touch screen sensor.

In FIG. 2, the sensing unit 110 and the dummy unit 110′ are formed in alinear shape, but the present invention is not limited thereto and maybe formed in various pattern shapes. For example, the overall shape ofthe sensing unit 110 may have a diamond, a trapezoid, a rhombus, and thelike.

Meanwhile, the electrode is an electrode provided in order to transmitthe touch signal sensed from the sensing unit 110 to an external drivingcircuit (not shown) and may be simultaneously formed when the sensingunit 110 and the dummy unit 110′ are formed. In the present invention,since the details for the electrode is beyond the scope of the presentinvention, the more detailed description thereof is omitted.

In the case of including the sensing unit 110, the dummy unit 110′, anda sensing connecting unit 120 connecting the sensing units 110 or adummy connecting unit in the substrate for the touch screen sensoraccording to the exemplary embodiment, the dummy connecting unit (notshown) connecting the dummy units 110′ may be formed by electrodesconnected to each other in the same or a similar pattern having apredetermined direction. In the exemplary embodiment, the pattern havinga predetermined direction is a continuous pattern, and as illustrated inFIG. 2, may be a lattice-shaped pattern where lines formed in thepredetermined direction cross each other.

In the exemplary embodiment, the same or similar pattern may includepatterns of which repeated cycles and repeated shapes are geometricallythe same and the repeated cycles and repeated shapes are formed in anacceptable error range which is predetermined by software.

Accordingly, in the exemplary embodiment, in the case of including theelectrode patterns of the sensing unit 110 and the dummy unit 110′ andthe sensing connecting unit 120 and the dummy connecting unit whichconnect the sensing units 110 and the dummy units 110′, the electrodepattern of the dummy connecting unit (not shown) is the same, therebyreducing visibility of the sensing unit 110 recognized by the user.

The pattern having the predetermined direction is formed in a continuouspattern, and a part of the pattern may be disconnected on a boundary ofthe dummy unit 110′. The disconnection of the part of the pattern may beformed when an edge of the pattern of the dummy connecting unit (notshown) is opened, in the case where the sensing unit 110, the dummy unit110′, the sensing connecting unit 120, and the dummy connecting unit areincluded.

As described above, the disconnection of the part of the pattern on theboundary of the sensing unit 110 and the dummy unit 110′ means that thesensing unit 110 and the dummy unit 110′ are electrically insulated fromeach other, and the opened edges of the patterns of the sensing unit 110and the dummy unit 110′ formed by the disconnection means that the edgesare not connected to edge electrodes as illustrated in FIG. 3. FIG. 3 isan enlarged view of a part of FIG. 2B, and referring to FIG. 3, sincethe edges are opened, the problem in that the continuity disappears tobe disconnected by connecting the edges to the edge electrodes is solvedand the edges are separated from each other with a minute interval, buttaken as a whole, the electrodes are recognized to be continuous by theuser, thereby reducing visibility of the sensing unit 110.

In the exemplary embodiment, the opened edge means that the patterns arealternately formed to be long and short at the edges, and referring toFIG. 4, the sensing unit 110 or the dummy unit 110′ of FIG. 4 may beformed as a plurality of electrodes which are disposed so that lengthsof the electrodes become alternately short and long at the edges. In theexemplary embodiment, the alternation means that the short and longlengths are repeated according to an order, and referring to referencenumeral 110 a of FIG. 4, long and short electrodes are alternatelyrepeated at the edges or regularly or irregularly repeated according toa predetermined pattern in FIG. 4.

In the exemplary embodiment, the pattern may be a lattice-shaped patternin which lines formed in a predetermined direction cross each other asillustrated in FIG. 2. The lattice-shape in which the lines formed in apredetermined direction cross each other means that a lattice-shapedpattern of a net shape or a mesh shape is entirely formed.

The lines crossing each other of the lattice-shaped pattern may have thesame line width and pitch defining an interval between the lines or havea line width and a pitch having predetermined similarity. In theexemplary embodiment, the same line width or pitch or the line width orpitch having predetermined similarity means that the line width andpitch have values in a predetermined range represented by Table 1 so asto acquire predetermined fill factors.

TABLE 1 Line width (μm) Pitch (μm) Fill Factor (%) 1~5  100 1.9~10  2002.5~5.0 300 1.9~3.5 400 1.4~2.5 500 0.4~1.9 600 0.3~1.7 6~10 100 11~19200 5.9~10  300 3.9~7.0 400 2.9~5.0 500 2.3~3.9 600 1.9~3.3

Referring to FIG. 5 and Equation 1, the fill factor is defined as aratio of dividing an area where an electrode layer (means an electrodelayer formed by the dummy unit 110′ and the sensing unit 110) isoccupied by an area of a lattice-shaped pattern (shape of the dummy unit110′ or the sensing unit 110) formed on one substrate or anylattice-shaped substrate represented by laminating a multiple substrate,and is represented by the following Equation 1.

Fill factor(%)=100−[[(horizontal pitch−line width)×(vertical pitch−linewidth)/(horizontal pitch×vertical pitch)]×100]  [Equation 1]

When the defined fill factor is smaller than 1.4, transmittanceincreases, but resistance of the electrode layer rises and a contactarea of capacitance is reduced, and as a result, a touch operation maynot be smoothly performed, and when the fill factor is larger than 10,an area of the electrode layer occupied in the substrate is large, andas a result, transmittance is deteriorated and the pattern isrecognized.

Accordingly, the fill factor may have values of preferably 1.4 to 10.0%and more preferably 1.4 to 7.0%. The line width and the pitch may beproperly controlled according to a value of the fill factor.

In the exemplary embodiment, the lattice-shaped lines crossing eachother may be tilted according to a predetermined angle. Referring toFIG. 4, the lines formed in the exemplary embodiment has a patternhaving a shape tilted by 45° based on a horizontal axis, and the tiltedshape increases accuracy of the sensing by increasing a ratio ofelectrodes for sensing a touch input per unit area, and thepredetermined tilted angle may be an angle determined in order toprevent a moire phenomenon from occurring due to a mutual interferencebetween a pattern having a predetermined direction and a patterndifferent from the pattern. In the exemplary embodiment, theinterference between the pattern and the different pattern may be aninterference caused by electrodes formed on the substrate by laminatinga plurality of substrates which sense touch positions of differentdirections, or may be caused by patterns formed by a plurality of pixelsincluded in an image information display unit displaying imageinformation.

The moire phenomenon means a natural interference phenomenon formed inthe case where two independent periodic patterns are laminated at apredetermined angle. The moire pattern means a strength fluctuation of awave shape, a ripple shape, and a small wisp shape which seems to belaminated with a display image of the screen.

In the exemplary embodiment, preventing the occurrence of the moirephenomenon may mean that a torsion is applied according to a firstpredetermined angle between directions of patterns so that strengthfluctuations of a wave shape, a ripple shape, and a small wisp shapewhich seems to be laminated with a display image of the screen are notgenerated by laminating the patterns by preventing the mutualinterference of the patterns, or the strength fluctuations formedaccording to lamination is not recognized by the user. The “notrecognized by the user” means that a repeated interval of a third formedpattern is an interval of a resolution or less which defines a intervalcapable of being discriminated by naked eyes of a person.

In the exemplary embodiment, the tilted angle includes an angle capableof being differently determined according a line width and a pitch inaddition to the angle shown in FIG. 4. In the exemplary embodiment,since the pattern having the predetermined direction has a predetermineddirection based on the tilted pattern, in the case where the sensingunit 110, the dummy unit 110′, the sensing connecting unit 120, and thedummy connecting unit are included, the dummy connecting unit (notshown) may be formed of electrodes connected to each other in a patternhaving the same or a similar direction as or to the tilted pattern.

Referring to FIG. 6B, the substrate for a touch screen sensor accordingto the exemplary embodiment includes a base 100 b, a resin layer 100 aand an electrode layer 112.

The base 100 b may be formed of a transparent base 100 b. That is, asthe base 100 b having predetermined transparency, the transparent base100 b may be formed in a transparent thin film form by using at leastone of polyethylene terephthalate (PET), polyimide (PI), acryl,polycarbonate (PC), triacetate cellulose (TAC), polymethyl methacrylate(PMMA), polyethersulfone (PES), polyethylene naphthalate (PEN), orglass.

The resin layer 100 a is laminated on the base 100 b and has a patternedintaglio on one surface. In detail, the resin layer 100 a is laminatedon the transparent base 100 b, and the intaglio shape is formed byimprinting a mold having an embossed shape corresponding to a desiredintaglio shape on the resin layer 100 a. That is, the intaglio is formedon the resin layer 100 a by using the mold having the embossed shape.Accordingly, one or more intaglio forms any pattern. A cross section ofthe resin layer 100 a with the intaglio may have an intaglio shape ofany one of a quadrangle, a triangle, and a trapezoid. When the embossedshape of the mold is a quadrangle, the intaglio shape formed on theresin layer 100 a is a quadrangle, and when the embossed shape of themold is a triangle, the intaglio shape formed on the resin layer 100 ais a triangle, and when the embossed shape of the mold is a trapezoid,the intaglio shape formed on the resin layer 100 a is a trapezoid. A‘width’ of the intaglio in the resin layer 100 a may be in the range of1 μm to 10 μm, a ‘depth’ may be in the range of 1 μm to 10 μm, and a‘pitch’ between the intaglios may be in the range of 200 μm to 600 μm.Of course, this case just corresponds to an exemplary embodiment, andthe width, depth and pitch of the intaglio may be variously modified.The resin layer 100 a may be implemented by an ultraviolet (UV) resin ora thermosetting resin.

The electrode layer 112 is formed by filling a conductive material inthe intaglio, and in the case where the sensing unit 110, the dummy unit110′, the sensing connecting unit 120, and the dummy connecting unit areincluded, the dummy connecting unit (not shown) is formed on theelectrode layer 112. Here, examples of the conductive material mayinclude copper (Cu), silver (Ag), aluminum (Al), nickel (Ni), chromium(Cr), nickel-phosphorous (Ni—P), and the like.

The sensing unit 110 and the dummy unit 110′ may be simultaneouslyformed and made of the same conductive material, but as described above,the sensing unit 110 is an electrode which senses and transmits a touchsignal and is electrically active, and the dummy unit 110′ is anelectrode which is electrically inactive.

The substrate for a touch screen sensor according to the exemplaryembodiment may further include a black layer 114 configured to reducevisibility of the dummy connecting unit (not shown) in the case wherethe sensing unit 110 formed on the electrode layer 112, the dummy unit110′, the sensing connecting unit 120, and the dummy connecting unit areincluded, and the black layer 114 may be laminated above the electrodelayer 112 of the intaglio or between the resin layer 100 a and theelectrode layer 112.

Although not illustrated, insulating layers which are laminated on thesensors 100 and 200 may be further included in the first sensor 100 andthe second sensor 200. Here, the insulating layer may includepolyethylene terephthalate (PET) and a coating having transparencylaminated on the PET, and an anti-reflection (AR)—low reflection(LR)—antiglare coating (AG) layer may be further laminated on theinsulating layer so as to reduce reflectance of external light in atouch screen panel.

The first sensor 100 of the touch screen sensor according to theexemplary embodiment includes a plurality of first dummy units 110′which are adjacent to the first sensing units 110 and formed byelectrodes which are connected to each other in a pattern having thesame or a similar direction as or to the first pattern to reduce thevisibility of the sensing unit 110, and first sensing connecting units120 formed by electrodes which are connected to each other in thepattern having the same or a similar direction as or to the firstpattern and connecting the first dummy units 110′, and the first dummyunit 110′ may be included at a position corresponding to the secondsensing unit 210 on one side of the base.

In the exemplary embodiment, the first sensor 100 and the second sensor200 may adhere to each other in a direction that the first sensing unit110 formed in the first sensor 100 and the second sensing unit 210formed in the second sensor 200 cross each other. That is, if the firstdirection of the first sensing unit 110 is a y direction on a coordinateaxis, the second direction of the second sensing unit 210 adheres to thefirst direction so as to be an x direction on the coordinate axis.

In this case, the second dummy unit 210′ is formed in the second sensor200 at a position corresponding to (facing) the first sensing unit 110,and the first dummy unit 110′ is formed in the first sensor 100 at aposition corresponding to (facing) the second sensing unit 210.

Accordingly, the first sensing unit 110 and the second sensingunit 210 are alternately disposed to be formed so as to calculatecoordinates thereof when the touch signal of the user is inputted.

In the exemplary embodiment, the first sensor and the second sensor maybe formed on one side and the other side of the same base as describedabove, or may be formed on different bases, respectively.

Even in the case where the first and second sensors are formed ondifferent bases, similarly to the case where the first and secondsensors are formed on the same base, the first sensor and the secondsensor may adhere to each other in a direction that the first sensingunit formed in the first sensor and the second sensing unit formed inthe second sensor are perpendicular to each other. That is, if the firstdirection of the first sensing unit is a y direction on a coordinateaxis, the second direction of the second sensing unit adheres to thefirst direction so as to become an x direction on the coordinate axis.

In this case, the second dummy unit is formed in the second sensor atthe position corresponding to the first sensing unit, and the firstdummy unit is formed in the first sensor at the position correspondingto the second sensing unit. The first dummy unit may be formed on oneside of the base corresponding to the position of the second sensingunit, and on the contrary, the second dummy unit 210′ may be formed onthe other side of the base corresponding to the position of the firstsensing unit. A touch screen panel according to an exemplary embodimentof the present invention includes an image information display unit anda touch screen sensor.

The image information display unit displays image information by using aplurality of pixels. In the exemplary embodiment, the image informationdisplay unit may include image display devices such as a liquid crystaldisplay (LCD), a plasma display panel (PDP), an organic light emittingdiode (OLED), and an active matrix organic light emitting diode (AMOLED)which are used in mobile devices such as a mobile phone, personaldigital assistants (PDA), and a portable multimedia player (PMP).

The touch screen sensor includes the first sensor and the second sensor.In the exemplary embodiment, the first sensor includes a plurality offirst sensing units formed by electrodes connected to each other in afirst pattern having a first predetermined direction on one side of thebase positioned on the upper surface of the image information displayunit and a first sensing connection unit formed by electrodes which areconnected to each other in a pattern having the same or a similardirection as or to the first direction and connecting the first sensingunits.

Hereinafter, first and second sensors correspond to the first and secondsensors 100 and 200 of the substrate for a touch screen sensor or thetouch screen sensor described above, and thus the detailed descriptionthereof is duplicated and omitted.

Hereinafter, a process of forming an electrode by forming and filling anintaglio in a resin layer according to at least one exemplary embodimentof the present invention will be described. FIG. 8 is a flowchartillustrating a manufacturing method of a substrate for a touch screensensor according to an exemplary embodiment of the present invention.Referring to FIG. 8, a manufacturing method of a substrate for a touchscreen sensor according to the exemplary embodiment includes coating aresin layer (S100), molding an intaglio (S200), forming an electrodelayer (S300), and forming a black layer (S400).

In the coating of the resin layer (S100), the resin layer is laminatedon the base, and a resin film or glass may be sued as the base. The basemay be formed of a transparent base. That is, the base havingpredetermined transparency may be formed in a transparent thin film formby using at least one of the above materials. A thickness of the basemay be in the range of 25 to 250 μm in order to improve luminance, andlight transmittance may be 80% or more, and more preferably 90% or more.

In the molding of the intaglio (S200), the resin layer is imprinted by amold to form a patterned intaglio. In the case of using a UV curingresin or thermosetting resin as the resin layer 100 a, after a mold iscompressed with a material before curing and the resin layer 100 a iscured by applying UV or heat in the compressed state, the mold isremoved, thereby forming the intaglio. In this case, a mold having anembossed shape for forming the intaglio in the resin layer 100 a mayhave a haze of 4% or less after patterning the intaglio by using amaterial having a sufficiently low illuminance, and this is because theluminance deteriorates to have a bad influence on a product performancein the case where the haze is more than 4%. In the exemplary embodiment,since the sensing unit 110, the dummy unit and the connecting unit 120are formed through the forming of the electrode layer in which aconductive material is filled in the intaglio formed in the molding ofthe intaglio, in the molding of the intaglio according to the exemplaryembodiment, a structure of the electrode of the substrate for the touchscreen sensor is formed of the intaglio.

Accordingly, in the molding of the intaglio (S200), the intaglios aremolded in order to form the sensing units 110 formed in a pattern havinga predetermined direction on one side of the base and the connectingunits 120 formed in a pattern having the same or a similar direction asor to the direction of the pattern and connecting the sensing units 110.In the case where dummy units and dummy connecting unit which areadjacent to the sensing units 110 and formed in a pattern having thesame or a similar direction as or to the direction of the pattern toreduce visibility of the sensing units 110 are included, the molding ofthe intaglio further includes molding an intaglio for forming dummyconnecting units (not shown).

As described above, in the exemplary embodiment, the pattern having thepredetermined direction is formed in a continuous pattern, but a part ofthe pattern may be disconnected on a boundary of the sensing unit 110and the dummy unit. That is, in the case where the sensing unit 110, thedummy unit, the sensing connecting unit 120, and the dummy connectingunit are included, edges of the patterns of the dummy connecting unit(not shown) may be opened. The “part of the pattern is disconnected on aboundary of the sensing unit 110 and the dummy unit” means that thesensing unit 110 and the dummy unit are electrically insulated from eachother, and the “disconnected” means that the edges of the patterns ofthe sensing unit 110 and the dummy unit are not connected by edgeelectrodes.

Since the edges are opened to be connected to the edge electrodes asdescribed above, the problem in that the continuity disappears to bedisconnected is solved and actually, the edges are separated from eachother with a minute interval, but taken as a whole, the electrodes arerecognized to be continuous by the user, thereby reducing visibility ofthe sensing unit 110. In the exemplary embodiment, the “edges areopened” means that the patterns are alternately formed to be long andshort at the edges, and the sensor or the dummy unit may be formed as aplurality of electrodes which are disposed so that lengths of theelectrodes become alternately short and long at the edges.

The pattern formed in the molding of the intaglio (S200) according tothe exemplary embodiment may be a lattice-shaped pattern in which linesformed in a predetermined direction cross each other, and the linescrossing each other of the lattice-shaped pattern may have the same linewidth and the same pitch defining an interval between the lines or havea line width or pitch having predetermined similarity. In the exemplaryembodiment, the lattice-shaped lines crossing each other may be tiltedaccording to a predetermined angle.

In the forming of the electrode layer (S300), a conductive material isfilled in the intaglio formed in the molding of the intaglio (S200), andin the case where the sensing unit 110, the dummy unit 110′, and theconnecting unit 120 are formed on the electrode layer 112 filled withthe conductive material in the forming of the electrode layer (S300).Here, examples of the conductive material may include copper (Cu),silver (Ag), aluminum (Al), nickel (Ni), chromium (Cr),nickel-phosphorous (Ni—P), and the like.

Accordingly, in the exemplary embodiment, the sensing unit 110 and thedummy unit 110′ may be simultaneously formed and made of the samematerial, but as described above, the sensing unit 110 is an electrodewhich senses and transmits a touch signal and is electrically active,and the dummy unit 110′ is an electrode which is electrically inactive.

In the forming of the electrode layer (S300), the electrode layer may beformed by forming a seed layer, and in more detail, a surface treatmentlayer, on which a surface treatment is performed in order to improveadhesion between a ‘seed layer’ to be formed on the inner surface of theintaglio and the surface of the resin layer 100 a and the ‘resin layer100 a’, may be formed.

As the surface treatment, chemical etching or catalyst treatment usingan alkali aqueous solution, plasma or ion-beam treatment, and the likemay be applied.

Thereafter, a metallic seed layer is formed on the surface treatmentlayer. The seed layer may be formed by an electroless plating, CVDdeposition, sputtering or printing method. In this specification, themetallic material means the aforementioned electrode material.Thereafter, the electrode layer is formed on the seed layer byelectroless plating, CVD deposition, sputtering, a coating method or aprinting method.

In a method of removing the seed layer from the surface of the resinlayer except for the intaglio pattern region, the seed layer formed onthe surface of the resin layer is selectively removed by filling a resinhaving an anti-etching property in the intaglio which is the patternregion and then depositing the filled resin in an etchant. In this case,a chemical used for etching includes any one of nitric acid, sulfuricacid series, hydrochloric acid, copper sulfate, ferric chloride, andcopper chloride.

In the forming of the electrode layer (S300), an electrode may be formedin the intaglio of the resin layer without the seed layer, and in moredetail, the forming of the electrode layer in the intaglio without theseed layer is to remove a remaining material on the surface of the resinlayer 100 a by a blade after coating a conductive material on thesurface of the resin layer 100 a and the intaglio. In more detail, theconductive material is coated on the resin layer 100 a without ametallic seed layer and the remaining material is wiped and scraped byusing a blade so as not to remain on other surfaces, therebymanufacturing a substrate for a touch screen panel.

In the forming of the black layer (S400), a conductive black material islaminated above the electrode layer 112 of the intaglio formed in theforming of the electrode layer (S300). In the exemplary embodiment, inthe forming of the black layer (S400), as described in FIG. 6B, theblack layer 114 is laminated to reduce visibility of the electrode layer112.

Hereinafter, a cross-sectional structure of the touch screen panel inthe exemplary embodiment will be described.

In the touch screen panel according to the exemplary embodiment, twosubstrates are laminated on a liquid crystal panel (LCD panel), and eachsubstrate is made of a UV resin, PET, and hardcoating. That is, eachsubstrate may be constituted with a resin layer including an electrodelayer, a PET laminated on the resin layer, and a hardcoating having apredetermined hardness or more laminated on the PET, and the substratesmay adhere to each other by an adhesive layer (OCA) and may also adhereto each other by interposing the adhesive layer (OCA) between thecoating and the resin layer.

The touch screen panel according to the exemplary embodiment may beconfigured by laminating an AR/LR/AG layer on the uppermost side of thetouch screen panel.

The touch screen panel according to the exemplary embodiment may beconfigured by forming the adhesive layer (OCA) on the uppermost side ofthe touch panel and laminating at least one of glass, acryl, and atransparent base having a predetermined hardness or more.

The touch screen panel according to the exemplary embodiment may beconfigured by laminating an AR/LR/AG layer on the uppermost side of thetouch panel.

In the touch screen panel according to the exemplary embodiment, atleast one of glass, acryl, and a transparent base having a predeterminedhardness or more is provided on the adhesive layer (OCA) interposedbetween the liquid crystal panel (LCD panel) and the substrate.

In the touch screen panel according to the exemplary embodiment, atleast one of glass, acryl, and a transparent base having a predeterminedhardness or more is provided on the adhesive layer (OCA) interposedbetween the liquid crystal panel (LCD panel) and the substrate.

In the touch screen panel according to the exemplary embodiment, twosubstrates are laminated on the liquid crystal panel (LCD panel), and alower substrate is made of a UV resin, PET, and hardcoating. That is,the lower substrate is constituted with a resin layer including anelectrode layer, a PET laminated on the resin layer, and a hardcoatinghaving a predetermined hardness or more laminated on the PET.

On the contrary, an upper substrate is configured by laminating at leastone of glass, acryl, and a transparent base having a predeterminedhardness or more. That is, the upper substrate is constituted with aresin layer including an electrode layer and at least one of glass,acryl, and a transparent base having a predetermined hardness or morelaminated on the resin layer, and the upper substrate and the lowersubstrate may adhere to each other by the adhesive layer (OCA). Thesubstrates may adhere to each other on the coating of the lowersubstrate and the resin layer of the upper substrate by interposing theadhesive layer.

The touch screen panel according to the exemplary embodiment isconfigured by laminating an AR/LR/AG layer on the uppermost side of thetouch panel.

In the touch screen panel according to the exemplary embodiment, atleast one of glass, acryl, and a transparent base having a predeterminedhardness or more is laminated on the liquid crystal panel, and a lowersubstrate where the resin layer including the electrode layer islaminated thereon and an upper substrate where one of glass, acryl, anda transparent base having a predetermined hardness or more is laminatedon the resin layer including the electrode layer adhere to each other bythe adhesive layer.

In the touch screen panel according to the exemplary embodiment, anAR/LR/AG layer is laminated on the uppermost side of the touch panel. Inthe touch screen panel according to the exemplary embodiment, thesubstrate where one of glass, acryl, and a transparent base having apredetermined hardness or more is laminated on the resin layer, theresin layer is laminated thereon, and the coating having a predeterminedhardness or more is laminated on the resin layer adheres to the liquidcrystal panel by the adhesive layer.

In the touch screen panel according to the exemplary embodiment, thesubstrate where the resin layer including the electrode layer islaminated, one of glass, acryl, and a transparent base having apredetermined hardness or more is laminated on the resin layer, theresin layer is laminated thereon, and the AR/LR/AG layer is laminated onthe resin layer adheres to the liquid crystal panel by the adhesivelayer.

In the touch screen panel, a layer selected from any one of glass,acryl, and a transparent base having a predetermined hardness or more islaminated on a boundary, and the resin layer laminated on the upper andlower portions of the selected layer may be laminated so that theelectrode layer included in the resin layer does not directly contactthe selected layer. The reason is that the resin layer including theelectrode layer formed in the intaglio may directly adhere to the layerselected from any one of glass, acryl, and a transparent base having apredetermined hardness or more, such that an amount of the adhesive usedmay be reduced and as a result, a manufacturing cost may be reduced.

Meanwhile, in the case of the touch screen panel having the structure inwhich the intaglio of the resin layer is in contact with the LCD panel,when the resin layer is in contact with the LCD panel, the intaglioformed in the resin layer serves as illumination, thereby deterioratingimage quality on the display. Therefore, in order to improve theproblem, the OCA or the adhesive needs to be filled in the intaglio ofthe resin layer including the electrode layer.
